Design specifications, besides the safety of the operators, included the quick repair of damage sustained in enemy engagements, ability to traverse rough and often hazardous terrain, and cost effectiveness. Comparable to modern self propelled guns, the engine is placed in the fore, allowing greater room in the aft and extra protection from frontal assault. With this added space the Merkava can serve other roles besides that of and MBT; it has a platform for medical disembarkation, a forward command and control station, and can serve as an infantry fighting vehicle. The Merkava is a versatile and multipurpose vehicle and even includes a 60mm mortar.
